Rep. Ron Paul (R-Texas) suggested Monday while speaking at the University of New Hampshire that President Barack Obama could be impeached for the killing of U.S.-born al Qaeda cleric Anwar al-Awlaki in a drone strike in Yemen. Paul said an "impeachment process would be possible," according to The Hill. He added, "You could do more investigating into this. I put responsibility on the president. This is obviously a major step in the wrong direction." The libertarian-leaning presidential candidate said Friday that the killing amounted to an "assassination." He said America's leaders must think hard about "assassinating American citizens without charges."Despite his libertarian views, which sometimes put him at odds with the GOP, Paul has had much success with his "money bomb" fundraising and has substantial organization in early states.Paul has already said that Obama's decision to authorize military action in Libya without congressional approval was an "impeachable offense." But Paul said Monday that calling for the president's impeachment was typical for him: "I just said almost every president I've known I'd probably have to vote for impeachment, because there's very little respect for the Constitution -- and certainly there's no respect for the Constitution for assassinating American citizens."
